Quintessence Sky continues the story begun with Quintessence (Tor Books, 2013). At the edge of the flat Earth, a strange fire burns in the sky, weakening the power of the island and sparking war between human and manticore. Deep in the mountains, an age-old cycle has been interrupted, forcing the colonists to find and reverse it or die.
